TOY SCALE.

Application filed April 15,

The present invention relates to toy weighing scales, and its purpose isto provide an attractive article et this nature with a minimum ot movingparts with no possibility oftdisarrangement. The scale comprises ahousing, an integral pointer and pendulum eiement, and an integral trameand pan. rllhe transmitting connection between the beam and pointer issuch that movements given to the one will be positively imparted to theother with no possibility el' injuring or disengaging the connection,and this, ot course, is the desirable feature considering that thedevice is intended primarily as a toy.

An embodiment of the invention is shown in the accompanying drawingswherein Figure l is a side elevation ot the scale.

Figure 2 is a sect-ion on the line 2-2 et Fig. l.

Figure 3 is a top plan view,

Figure 4 is a perspective of the beam and integral pan, and

Figure 5 is a perspective orp the integral pointer and pendulum.

Referring to the drawings, the scale housing is composed of front andrear castings i0 and ll which by reason ot interlocking lugs such as l2are adapted to be held 'tegether by a single bolt i3, and by reason etabutting marginal flanges form a hollow body. These castings haverespective upright port-ions which have been designated as lO and ll,and horizontally extending pertions le and l5. 'lhe horizontal portionshave integral uprights or stanchi ons 1G and li' vespec-tively, andthese are recessed at their tops te receive the kniib edge bearings land i9 formed integrally with and bet-veen )cam 2O and pan 2l.

At its iiree end beam 2O is provided with a counterweight 22 and a pin23. 'lhe proportion oit the parts such that the center et gravity ot' thbeamand pan is brought intermediate the knife edges and the pin so thatconsidering the beam to be mounted on its supports, weig it 22 will tendto move the pai upwardly.

fis clearly shown in Fig. 27 beam 2O extends into the ca ity betweenwalls l0 and ll through a suitable aperture formed by cutting` awayportions of the marginal langes mentioned above. From the desorptionthus tar, it will be seen that the beam is mounted for pivotal movementabout bearings i8 and i s ib 1927. Serial No. 184,040.

19 with its end projecting` between the upright walls ot' the housing.

Mounted on bolt 13 tor oscillatory movements is pointer -3 provided withan aperture 2e through which the bolt extends. The pointer is extendeddownwardly beyond its pivotal point into an expanded portion and acounter-weight 2G. Portion 25 is provided with a cam slot which extendsat an angle et substantially loo relative to the longitudinal line otthe pointer proper. The oscillatory movements et the pointer are limitedby the length ot slot 27, so that it is permitted to swing through thevertical a certain extent in each direction. rl`he counter-weight 26 andthe weight ot expanded portion atleet the balance ot the pointer so thatit is normally yieldingly urged towards its lett hand limit oti'iscillation7 as shown in Fig. l.

Fin of the beam, when the parts are assembled. engages a cam slot 27 andit will be seen that upon depression of pan 2l pointer 23 will be movedto the ight against the torce o fiounter-weight and In Figure 2 thespace between walls l0 and ll is shown as be ing so limited as toprevent disengagement of pin 23 from slot 27. Thus although the knifeedges 18 and 19 can be lifted from their seats, the beam and pointer cannever be disconnected as long as the casing elements are retained inoperative relation.

Casing clement lO is provided with a window and a scale ot any desiredcharacter 2? in klied on the inner 'face of wall ll. in the us.. klrelation to the pointer. lllall ll likewise provided with arcuate windowso that the nieren/unt et the pointer is i visible vfrom the rear oi'Vthe housing.

From the above description it will be seen that the device is ot theutmost simplicity. and thus extremely well adapted to its purpose.lllhile particular embodiment et the invention has nec farily beenshown, it to be .in erstood that this showing is not to be takenrestrictive and that the scope of the invention is indicated in thefollowing claims.

l. ln a device of the class described` a pointer element mounted foroscillatory movements, a pivo'tallv mounted beam cle ment, one et saidelements having a cam slot. and the other a pin engaging in said slotwhereby movements imparted to one of them are positively transmitted tothe other, said beam element being lateially expanded at one end to forma pan.

2. In a device of the class described, a pointer element mounted foroscillation within certain limits, a pivotally mounted beam element,conneetin g means between the beam and pointer elements whereby angularmovements of the former are transmitted to the latter, and acounter-weight integrally formed on said beam element at one end thereofwhereby said pointer element is normally yieldably held in a limitposition, the other end ol iid beam element being laterally expanded toform a pan.

In a device of the class described, a pointer element mounted foroscillation, said element having a cam slot formed in an integralportion thereof, and a pivotally mounted beam element, said beam elementhaving a pin engaging in said cam slot whereby angular movements of saidbeam element are transmitted to said pointer element.

4. In a device of the class described, a vertical pointer elementmounted for oscillation, said element having a cam slot formed in anextension thereof below its pivot point, and a pivotally mountedhorizontal beam element. said beam element having a pin engaging in saidcam slot whereby angular movementsel'. said beam element are transmittedto said pointer element.

In a device of the class described, a vertical pointer element mountedfor oscillation, said element having a cam slot formed in an extensionthereof below its pivot point, said slot extending at an angle ofsubstantially 45 relative to the longitudinal line of said pointer, anda pivotally mounted horizontal beam element, said beam element having apin engaging in said cam slot whereby angular movements of said beamelement are transmitted to said pointer element.

6. In a device of the class described, a vertical pointer elementmounted for oscillation, said element having a cam slot formed in anextension thereof below its pivot point, said slot extending at an angleof substantially 450 relative to the longitudinal line of said pointer,and a pivotally mounted horizontal beam element, said beam elementhaving a pin engaging in said cam slot whereby angular movements of saidbeam element are transmitted to said pointer element to move the latterin the same angular direction.

7. Structure according to claim 4t wherein a counterweight .is providedon the pointer element below the cam slot'to urge it yieldingly in onedirection of oscillation.

8. Structure according to claim 4 wherein a counterweight is provided onthe beam element to urge it yieldingly in one pivotal direction.

9. Structure according to claim 4. wherein counterweights are providedon both the beam and pointer elements to urge them yieldingly in thesame angular direction.

10. In a device of the class described, an integral pendulum and pointereleu'ient mounted for oscillatory movements, a pivotally mounted beamelement, and a cam slot and pin connection between said elen'ientswhereby movements of the one are positively transmitted to the other.

ll. In a device of the class described, a pointer element mounted foroscillation, a pivotally mounted beam element, a separable transmittingconnecting means between said elements, and a housing having oppositewalls positioned to maintain said connectin g means operative.

l2. In a device of the class described, a pointer element mounted foroscillation, a cam groove in a portion of said element, a beam elementfulcrumed on open bearings, a laterally extending pin on said beamelement engaging in said cami slot whereby movements of the beam elementare transmitted to the pointer element, said pin being diseu gageablefrom said slot upon a relative lateral movement of the two elements, anda housing having walls adapted to abut said elements to prevent suchrelative movement.

13. In a device of the class described, an integral pendulum and pointerelement mounted for oscillatory movements, a pivotally mounted beamelement, one of said elements having an integral part formed with a camsurface, and means on the other of said elements engaging said camsurface, whereby weighing movements of said beam elements aretransmitted to the pointer element.
